Tramway system in the Thai city of Chiang Mai, included in the city’s Master Plan, with the aim of implementing a massive transport system to improve citizen’s mobility and reduce traffic congestion.

The tramway runs on pneumatic tires, which leads to higher traction, and thus to higher acceleration and braking capacity. As a consequence, commercial travel-times are lower compared to those systems running on rails.

In addition, the infrastructure required for this purpose only involves the construction of a single guide rail, as pneumatic tires run on concrete slabs that can also be used by the rest of vehicles on the road.

The proposed network would cover 4 lines in addition to a tramway branch from A1 line connecting to the Airport. 3 lines are of two-way configuration while line number 4 is a circular one-way line running counterclockwise. The total length of the network is 110 km.

This project included the preliminary study of the tramway line as well as all facilities and supplementary buildings together with a study of alternatives. The services provided were:
